摘要
通过分析测试国内外氧化锌电阻片的电气性能结果及化学成分,发现电气性能优异的原因是在配方中未添加Cr_2O_3和SiO_2成分,而添加了其他微量元素,从而改变了烧成后电阻片的微观结构。通过参考引证有关研究文献和专利,研发出的新型氧化锌电阻片配方的电气性能效果较好。
Through the test and analysis on the electrical pertormance and chemical composmon ot zinc oxide varistor at home and abroad, it is found that the reason of the Excellent eLectrical properties is the composition of Cr2O3 and SiO2 were not added in its formula, and other trace elements were added,thus the microstructure after firing varistor was changed. By citing the relevant research literature and patents, the electrical performance for the formula of the developed new type ZnO varistor has better effect.
